How do you properly shuffle tarot cards?

Shuffle your tarot cards any way you like. I like to shuffle my cards Vegas style. The key is to keep them face down so you don't look at the pictures. Also, keeping the focus of your question in mind while you shuffle is of utmost importance. If you're not really thinking, if you're not really tapped into your question while you shuffle the cards, you're wasting your time. You want to be able to visualize your question as much as possible.
